Vitinho is highly-rated within the Brasileiro Série A team but at 19 years old is not a regular feature in the side.
And with the no Brazilian reserve league to speak of, Cuca feels the young star would benefit from playing regular competitive football.
The manager said: “I’ve heard something about it. I think it’s great for the player and the club.
“Here, we do not have B teams. He does not play here, but he has been training relatively well.
“If he leaves, if he stays, fine. If he does not stay, he will return much more prepared.
“A while back we had a B [team] to play. Tomorrow [Thursday] we have a [reserve] game against Sao Caetano and he is going to play.”
Barcelona would reportedly need to spend €1.5million to sign the player on loan until June 2018.
